Definitions

  • vacuum packaging is a particular packaging technique which consists in storing substances, products and various objects, even clothing and garments, inside an envelope from which the air has been eliminated by means of suction.
  • the main and widespread use of vacuum packaging is in food storage because the majority of bacteria and micro-organisms cannot proliferate in the absence of air, and this allows the food, whether cooked or raw, to be stored longer.
  • the food advantageously keeps its nutritional properties, flavor, aroma and also natural color unaltered under these storage conditions.
  • the main advantage of vacuum storage under controlled atmosphere is ensuring longer storage of the food and organoleptic properties thereof, and it is particularly recommended for improving and lengthening the storage time of fresh pasta.
  • Vacuum packaging machines in controlled atmosphere on the market are the so-called chamber machines essentially comprising a base frame that supports:
  • the bag (or sachet), with the product to be packaged, is introduced into the tank while ensuring the nozzles are inserted in the bag itself through the open edge of the bag.
  • the open edge of the bag is therefore rested on the welding bar and the cover is lowered, thus creating a chamber communicating with the vacuum pump between the cover and the tank.
  • the air extraction is stopped and a gas or a mixture of protective gases listed above is introduced into the bag through the nozzles to create, in the bag, a protective atmosphere that surrounds and protects the product.
  • the welding counter-bar and the underlying welding bar are mutually forced against each other to weld the edge of the bag comprised therebetween.
  • the atmospheric pressure is restored in the tank, the cover thereof is opened and the packaged bag is removed from the tank.
  • the chamber vacuum packaging machines now described have features of increased reliability and versatility, making them adapted to packaging a large variety of products.
  • chamber vacuum packaging machines now described are limited by having an intermittent cycle, and therefore they are not adapted to continuously package large quantities of multiple types of food.
  • vacuum packaging machines in controlled atmosphere are provided and widespread on the market, these packaging machines essentially comprising two tanks for containing the food to be packaged and a single cover that tilts so as to alternatively cover one or the other tank, in each of which the vacuum packaging is alternately produced.
  • the two tanks are alongside each other and an operator loads the food to be packaged in a first tank, while the vacuum packaging process is being performed in the second tank, which is closed by the cover.
  • the packaged product is removed from the first tank at the end of packaging, and the cycle is repeated by introducing the new product to be packaged into the second tank.
  • the conveyor belt E transfers the preformed bags B with the products therein which the operators O arranged thereon from the loading area F up to the packaging area G, where there is a packaging chamber H.
  • the injector nozzles 14 and the preformed bags B they support therefore are movable together with the conveyor belt 4 itself, and this advantageously allows creating the vacuum and introducing the inert gaseous substance in atomized form into the different preformed bags B which are progressively to be packaged in a more continuous and quicker manner with respect to the known vacuum packaging machines, thus resulting in an improved hourly production for the vacuum packaging machine 1 of the invention with respect to the prior art, by a single operator who always remains stationary at the loading area 6 of the vacuum packaging machine 1 .
  • the vacuum packaging machine 1 herein claimed comprises a plurality of injector nozzles 14 belonging to the conveyor belt 4 which are configured to be connected to the preformed bags B and to be turned facing towards the inside of the latter when the preformed bags B are arranged on the conveyor belt 4 and used to spray atomized inert gas therein.
  • profile 19 a of each slit 19 is configured to receive the through insertion of the welding means 12 which are arranged at the packaging area 7 and are aligned with the longitudinal alignment directions X 2 of the slits 19 , as shown in particular in FIG. 7 .
  • FIG. 7 shows that each welding bar 12 a is associated with the work surface 3 below the conveyor belt 4 and that each welding counter-bar 12 b is opposed to the welding bar 12 a and is arranged inside the packaging chamber 8 , it being fixed to and protruding from the canopy 8 b of the packaging chamber 8 itself.
  • each pressure rod 32 advantageously and conveniently keeps the preformed bag B adhering to the injector nozzles 14 during the injection of the gaseous mixture, by means of gasket 33 with which it is provided.
  • the welding means 12 , the pressure rods 32 and the injector nozzles 14 which, as indicated, are supplied with the gaseous mixture directly from the collecting chamber 23 of the injection system 13 which is made in the thickness of the work surface 3 , are contained under these conditions inside the vacuum chamber 10 .
  • the passage of the gaseous mixture through the work surface 3 is allowed by the connecting means 16 that comprise the collecting chamber 23 , the inlet duct 29 and the outlet ducts 30 , which are made through the thickness of the work surface 3 .
  • control station provided with a dedicated software operatively connected to detection means (not shown or at least not marked with their own numeral below) that are configured to verify when the injector nozzles 14 are arranged at the respective outlet ducts 30 of the collecting chamber 23 and here, open the interception devices of the supply line 15 to supply the gaseous mixture to the injector nozzles 14 and inject it into the preformed or premade bags B.
  • detection means not shown or at least not marked with their own numeral below
  • Each welding bar 12 a and each welding counter-bar 12 b come into mutual contact and provide the welding of bag B comprised therebetween when:
  • the vacuum packaging machine of the invention also allows a vacuum packed product to be obtained which has improved storage conditions with respect to an equivalent product packaged by means of belt vacuum packaging machines of the known type.
